Principles of Operation
Roof Opening Panel - The roof opening panel assembly uses an integrated motor and module to operate the roof opening panel. The roof opening panel motor and module are installed new as an assembly. The roof opening panel is an electronically operated glass panel that can be opened, closed or vented by the roof opening panel switch. Actuating the switch in either a forward or rearward motion supplies a ground to the roof opening panel motor/module. The roof opening panel has an express open feature that is activated when the switch is momentarily pressed to the double detent OPEN position. This function is controlled by the roof opening panel motor/module.
The roof opening panel motor must be initialized when repairs are carried out on any part of the roof opening panel system, including: whenever the roof opening panel motor has been removed from the roof opening panel system, the roof opening panel glass has been removed from the roof opening panel system, the roof opening panel assembly has been removed from the vehicle, a new roof opening panel motor has been installed, a new roof opening panel glass has been installed or a new roof opening panel assembly has been installed.
Normal Operation
When the roof opening panel glass is completely closed, it is flush with the roof panel.
This pinpoint test is intended to diagnose the following
- Roof opening panel adjustment
- Roof opening panel seal/weatherstrip
- Roof opening panel and motor/module
When the roof opening panel glass is completely closed, it should be within specifications. Refer to SPECIFICATIONS .

PINPOINT TEST D: THE ROOF OPENING PANEL IS NOISY DURING OPERATION
- D1 CHECK THE ROOF OPENING PANEL FOR OBSTRUCTIONS OR DAMAGE Check the roof opening panel for any obstructions and damage. Are there any obstructions and/or damage? YES : REMOVE all obstructions. REPAIR any damage. If the damage cannot be repaired, INSTALL a new roof opening panel frame. REFER to «Roof Opening Panel - Exploded View»(ref-293467-S31183086162008080700000) and «Roof Opening Panel Frame»(ref-293467-S34744189802008080700000) . TEST the system for normal operation. NO : Go to D2 .
- D2 CHECK THE ROOF OPENING PANEL OPERATION Check the roof opening panel during operation. Is the roof opening panel loose or incorrectly adjusted? YES : ADJUST the roof opening panel. REFER to «Roof Opening Panel Alignment»(ref-293467-S38885178292008080700000) . TEST the system for normal operation. NO : Go to D3 .
- D3 CHECK THE ROOF OPENING PANEL TRACKS Open the roof. Check the roof opening panel tracks for obstructions and damage. Are the roof opening panel tracks OK? YES : Go to D4 . NO : REMOVE all obstructions and REPAIR any damage. If the roof opening panel tracks cannot be repaired, INSTALL a new roof opening panel frame. REFER to «Roof Opening Panel - Exploded View»(ref-293467-S31183086162008080700000) and «Roof Opening Panel Frame»(ref-293467-S34744189802008080700000) . TEST the system for normal operation.
- D4 CHECK THE ROOF OPENING PANEL SHIELD (SUNSHADE) Check the roof opening panel shield for correct movement. Is the roof opening panel shield moving correctly? YES : Go to D5 . NO : REMOVE and REINSTALL the roof opening panel shield. REFER to «Roof Opening Panel Shield»(ref-293467-S07156672042008080700000) . TEST the system for normal operation.
- D5 CHECK THE ROOF OPENING PANEL LIFTER ASSEMBLIES Check the roof opening panel lifter assemblies for obstructions and damage. Are the roof opening panel lifter assemblies OK? YES : Go to D6 . NO : REMOVE all obstructions and REPAIR any damage. If the roof opening panel lifter assemblies cannot be repaired, INSTALL a new roof opening panel frame. REFER to «Roof Opening Panel - Exploded View»(ref-293467-S31183086162008080700000) (Sunshade) and «Roof Opening Panel Frame»(ref-293467-S34744189802008080700000) . TEST the system for normal operation.
- D6 CHECK THE ROOF OPENING PANEL MOTOR/MODULE Remove the roof opening panel motor/module and leave the electrical connector connected. Operate the roof opening panel to the full OPEN and CLOSED position. Does the motor/module make excessive noise? YES : INSTALL a new roof opening panel motor/module. REFER to «Roof Opening Panel - Exploded View»(ref-293467-S31183086162008080700000) and «Roof Opening Panel Motor»(ref-293467-S22199766602008080700000) . TEST the system for normal operation. NO : REINSTALL the roof opening panel motor/module. TEST the system for normal operation. If the roof opening panel is still noisy, INSTALL a new roof opening panel frame. «Roof Opening Panel - Exploded View»(ref-293467-S31183086162008080700000) and «Roof Opening Panel Frame»(ref-293467-S34744189802008080700000) . If the roof opening panel is no longer noisy, the system is operating correctly. The concern may have been caused by an incorrectly installed roof opening panel motor.
The roof opening panel uses a integrated motor and module to operate the roof opening panel. A new roof opening panel motor/module is installed as an assembly.
The roof opening panel motor/module receives voltage from the accessory delay relay through circuit CBP41 (BU) when the key is in the ACC or RUN position and voltage at all times through circuit SBP19 (BU/RD). The roof opening panel motor/module provides ground to the roof opening panel switch through circuit CPR39 (VT/WH). When the roof opening panel switch is pressed to the CLOSE position, a ground signal is sent to the roof opening panel motor/module through circuit CPR40 (YE/OG), which causes the roof opening panel to close. When the roof opening panel switch is pressed to the OPEN position, a ground signal is sent to the roof opening panel motor/module through circuit CPR31 (VT/BN), which causes the roof opening panel to open.
